Question

Differentiate between meristematic and permanent tissues.

Answer 1

Hey friend,

Here's your answer,



☸ MERISTEMATIC TISSUE :-


✴ It generally has cells which are small, spherical or polygonal.


✴ The meristematic cells are under - differentiated.


✴ Cytoplasm is dense. Vacuoles are usually absent.


✴ No intercellular spaces.


✴ Cell wall of it's cells is thin.


✴ Nucleus of cells of this tissue is large and a prominent one.


✴ The cells undergo growth and division throughout their life.


✴ It contains cells which are metabolically active.


✴ It's cells are living.


✴ It provides growth to the plant body.


________________________________




☸ PERMANENT TISSUES :-


✔ It generally has cells which are large, and have different shapes.


✔ The permanent tissues have cells which are differentiated.


✔ Large central vacuole is present in living permanent cells.


✔ Intercellular spaces are present.


✔ Cell wall of it's cells maybe thin or thick.


✔ Nucleus of cells of this tissue is less prominent.


✔ Cells do not undergo division.


✔ Metabolism rate of cells of this tissue is slow.


✔ It's cells maybe living or dead.


✔ It is associated with the functions like :-


✒ Protection

✒ Support

✒ Storage

✒ Photosynthesis

Answer 2

Hey Friend,

Plant tissues are divided into two main categories based on the ability of their cells to divide...

ФMeristematic tissues - Keep on dividing and adding new cells to plants. They are responsible for plant growth.

ФPermanent tissues - Have lost their capacity to divide. They form the bulk of plant body.

⇒Merismetic tissues are of three types -
(i) Apical Meristem
(ii) Lateral Meristem
(iii) Intercalary Meristem

⇒Permanent tissues are of three types -
(i) Simple Tissues
(ii) Complex Tissues
(iii) Special Tissues

Differences between Meristematic and Permanent Tissues -

MERISTEMATIC TISSUES

1. Cells are small, isodiametric and undifferentiated. 

2. Cells may be rounded, oval, rectangular.

3. Cells are living and able to divide throughout plant life.

4. Intercellular spaces are absent.

5. Vacuoles are either absent or small.

6. Cell Wall is thin and formed of cellulose.

7. Cells are filled with cytoplasm.

8. Nucleus is large and central.

PERMANENT TISSUES -

1. Cells are large and differentiated or specialized to perform different functions.

2. Cells are of different shapes according to the type of permanent tissue.

3. Cells may be living or non-living, but without the power of cell division.

4. Intercellular spaces are often present.

5. A large, central vacuole is usually present.

6. Cell wall may be thin in some tissues but thick in others.

7. Cytoplasm forms a thin layer between the cell wall and vacuole.

8. Nucleus is relatively small and lies in the peripheral cytoplasm.
